DISTRIBUTION OF TRIBES. 431 
toits affinities. It has the peculiar habit of the dwarf species of 
Geigeria and similarly deeply lobed yellow corollas ; the receptacle, 
paleaceous under the female florets, but not under the sterlie 
florets of the centre, is that of Rhanterium ; but the female florets 
are in many rows, with short tubular corollas, as in the Conyzoid 
and many Grangeoid Asteroidew, and as in the Plucheines 
amongst Inuloides. The tailless anthers would exclude it from 
all Inuloid subtribes and place it technically, as proposed by 
De Candolle, among Asteroidez, where we might insert it after 
Heterothalamus in the Baccharis group. But it is in all other cha- 
racters, as well as in a geographical point of view, so perfect a 
stranger there that it seems preferable to class it next to Geigeria, 
as an exceptional form, such as is Barnadesia amongst Mutisiacez. 
The style does not help us; for, the disk-florets being sterile, it 
is undivided, as is the case so generaily in all tribes when similarly 
circumstanced. 
Two South-African genera, Osmites, with six species, and Os- 
mitopsis, with a single one, take their place among Buphthalmez 
in respect of almost all their general characters, as well as in habit 
(of Odontospermum) and the peculiar odour of the foliage; but 
the style is rather that of the South-African Athrixiew than of 
the more northern typical Buphthalme:e. 
There remains a small anomalous plant from a very different 
region, which, after being attached to various tribes, must perhaps 
find its resting-place next to Buphthalmesz. This is the Vablo- 
nium of Tasmania. Cassini placed it amongst Anthemidew. In 
working up the Australian flora, I had trusted perhaps rather too 
much to Bauer’s and Fitch’s elaborate drawings and analysis, and 
referred it, after some hesitation, to Helianthoidesm. A more 
careful examination shows that we had all overlooked the long 
setiform appendages or tails to the anther-auricles. This places 
it technically among Buphthalmex, with which also, notwith- 
standing its reduced size, the foliage and indumentum agree better 
than with Helanthoides. Anthemidee are quite out of the 
question. 
5. Helianthoidee. 
The tribe Helianthoidez is, again, one of the large ones. Not 
quite so numerous as Inuloides, it is still more varied. The 
species, rather under 1100, are distributed into about 140 genera 
not so easily classed into distinct subtribes as Inuloidex, rather 
more scattered geographically, and many of the smaller genera
